Sony KDL-32S2030

(1/3) > >>

OldLes:
I have a Sony KDL-32S2030 with sound but no picture.
Plug in, press "ON" and green LED lights up, relay clicks, and after a few seconds the backlight comes on. No OSD or pic. I don't have the genuine remote, but a multi purpose one will switch it to standby and back on OK. Red led in standby as expected.
I have checked all the PSU voltages according to indications on PSU board, and all present and correct.
With an input to the scart, I get sound OK, but no pic of any sort.
I THINK this is the WAX2 chassis, but though plenty of general info, no actual circuit diagrams.
Any suggestions, and does anybody have the manual?
Cheers, OldLes.

OldLes:
Well, we found time to play with this again today. On the main (BE) board, we found the three fuses, all of which were perfectly OK. (F7000, PS6000 and PS7000).
The T-con board seems to be part of the display section, so nothing in the manuals that could help. (We have both the training manual and of course the manual for the set, thanks to Jordan).
After carefully removing this T-con board, we examined it in detail (using both binocular microscope on Xs 10 mag), and a USB microscope. Nothing we could identify as a fuse, and all components do carry a circuit reference.
Any other advice, or do we scrap it? It does not seem that it can be much, but what?
Les.
